   I thought that make was smart enough that if you do have nested
#includes, it would pick this up. Am I wrong about this? That is, if
you have the following lines in the makefile:

aaa.c : bbb.h
bbb.h : ccc.h

and modified ccc.h, won't it know to recompile aaa.c? If so, the fgrep
method should be OK.
   As for the #include's with < >'s (system includes), I don't think
these are ever included in makefiles. If that's the case, then piping
the output from the "fgrep #include" through an "fgrep -v \<" should
take care of that problem. Anyway, I don't mean to argue about this;
the program you mentioned is probably a good thing to have.
   This discussion is really getting off from what the groups involved
are for, so I'm routing followups to comp.unix.questions.
